Abstract:
This paper proposes a virtual power plant optimization scheme of hybrid battery-hydrogen energy storage,which firstly analyzes the characteristics of each operation unit and establishes a cooperative operation optimization model,and secondly,on the basis of applying batteries in the virtual power plant,adds a hydrogen energy system consisting of electrolysis tanks,hydrogen storage tanks,and fuel cells in order to realize the hybrid energy storage of batteries and hydrogen energy system. Considering the theory of tariff-based demand response and stepwise carbon trading,the optimized operation costs and benefits of the virtual power plant with five different schemes are analyzed,and the example proves that the hybrid batteryhydrogen storage scheme of the virtual power plant for wind energy has a better economic performance.
